What is the bolt pattern and offset for the 86 turbo?

 

You didn't read the link I already posted, did you?

 

4 Lug bolt pattern: 4x4.5(4x114.3)
5 Lug bolt pattern: 5x4.5(5x114.3)
Studs are m12x1.25
Centerbore is 66.1mm

Stock wheel offset:

84-85 all(except AE): 30mm
86 non-turbo: 10mm
86 turbo: 20mm
87-89 Turbo: 30mm
87-89 non-turbo: 20mm
The stock tire size is 215-60-15 on 15x6.5 wheels, and 225-50-16 on the 16x7 wheels.


Here's my question.... so my wheels are a 20mm offset... what happens if i get wheels w/ a 40mm offset?

 

They won't fit without adapters. Will be too sunken in and will hit the strut tower.

Options you have:

Go with 87-89 Wheels like the pic below

or with the new 350Z wheels..you might be closer than I am with your 86 as the strut tower is different.
